Having come across this thread yesterday via my blog, I felt I ought to respond and bring any interested parties up to speed.
My name is Ian and I am one of the Directors of 'Artemis Engineering UK'; I can confirm that my company is still active and currently working to bring the Sawfly rifle to market. The main reason for everything taking so long is that the business is being run on a part time basis until we generate sufficient funding for it to begin paying its own way, until then I have a day job to keep paying the bills! My wife is also now working out a plan for raising money with a crowd funding campaign which will be launched soon, but you'll get the heads up on this through the blog so please do keep checking in with that.
The original plan was to have a single design that would meet all the legal criteria, allowing it to be concurrently marketed in Europe, Canada and the US; thus saving the hassle and costs of multiple tooling variations for specific customer bases.............In hindsight this was an error and one which took up a huge amount of time. Now we have a completed final design which will be produced solely for the US market. All the tweaking is done and the next step is to produce some Laser sintered 'demonstrator' rifles and the workshop drawings for the tooling to be manufactured from. The only major delay we forsee will be negotiating the BATFE approval system. Whether this would be an issue if the rifle was manufactured within the US is something that I need to look into (unless any of you fellas know already).
Although my blog uses photos of the MK2 prototype these will be updated with CAD images of the latest version; essentially they will be similar in layout and overall shape, but with slight modifications that go a long way to improve the Sawfly's usability and accuracy. Oh and before anyone asks, the trigger breaks at 2.5lb and is short, responsive and crisp!
I'll keep you posted. Thanks.
